nginx_substitutions_filter
-------
nginx_substitutions_filter is a filter module which can do both regular
expression and fixed string substitutions on response bodies. This
module is
quite different from the Nginx's Substitution Module. It scans the
output
chains buffer and matches string line by line, just like Apache's
mod_substitute.
To install, compile nginx with the following option:
--add-module=/path/to/this/directory
EXAMPLE
subs_filter_types text/html text/css text/xml;
